Unlike ordinary factory style LS iron blocks, our LSX engine blocks are purpose-built from the ground up using modern casting technology in a state-of-the-art foundry, utilising brand-new tooling to ensure superior consistency, density, and strength.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThis LSX block features extra-thick deck surfaces, beefier main webs, and more material throughout, making it far more resistant to cylinder pressure and block distortion compared to regular mass produced LS blocks. Unlike standard LS blocks (which use 4 head bolts per cylinder), the LSX allows 6 head bolts per cylinder, dramatically improving head sealing under boost or nitrous. It also features priority main oiling, ensuring critical bottom-end components get oil first which is crucial for high-RPM reliability.\u003c\/p\u003e\r\n\r\n\u003cp\u003eUnlike many mass-produced blocks, Proflow Warlord blocks are shipped mostly finished but intentionally left .005\" undersize on the cylinder bores, so your machine shop can hone them precisely to suit your pistons and application. This allows for a custom fit and optimal ring seal — critical for high-performance engines.\u003c\/p\u003e\r\n\r\n\u003cp\u003eSpecifications:\u003c\/p\u003e\r\n\r\n\u003cul\u003e\r\n\t\u003cli\u003eMax 4.070” finished bore\u003c\/li\u003e\r\n\t\u003cli\u003eCNC-machined HT250 cast-iron block\u003c\/li\u003e\r\n\t\u003cli\u003eDeck plate honed\u003c\/li\u003e\r\n\t\u003cli\u003eAlign-honed main bearings\u003c\/li\u003e\r\n\t\u003cli\u003eDeck height 9.240” \u003c\/li\u003e\r\n\t\u003cli\u003eBillet-steel main caps\u003c\/li\u003e\r\n\t\u003cli\u003eExtra-thick siamese cylinder bores\u003c\/li\u003e\r\n\t\u003cli\u003eLS7-style, 6-bolt dowel-located billet main bearing caps\u003c\/li\u003e\r\n\t\u003cli\u003eWet-sump and dry-sump oiling capability\u003c\/li\u003e\r\n\t\u003cli\u003eProduction-style deep-skirt head bolt holes\u003c\/li\u003e\r\n\t\u003cli\u003eMaintains production exterior accessory mounting provisions\u003c\/li\u003e\r\n\t\u003cli\u003eFront motor plate mounting holes added\u003c\/li\u003e\r\n\t\u003cli\u003eAdditional material cast around cam bearings for greater strength \u003c\/li\u003e\r\n\t\u003cli\u003e6-bolt cylinder head provision\u003c\/li\u003e\r\n\t\u003cli\u003eStandard 0.842\" lifter bores\u003c\/li\u003e\r\n\t\u003cli\u003eAccommodates all LS oil pumps and oil pans\u003c\/li\u003e\r\n\t\u003cli\u003eExternal oil pump feed (rear of block)\u003c\/li\u003e\r\n\t\u003cli\u003eUses LSX style camshaft retainer thrust plate\u003c\/li\u003e\r\n\t\u003cli\u003eUses LSX style rear main cover \u003cbr\u003e\r\n\t \u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Proflow","offers":[{"title":"Default Title","offer_id":55003076296917,"sku":"WAR-08160","price":4693.34,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0825\/0635\/0805\/files\/WAR-08160_22b11918-417f-46d6-910b-e8052c8cce3b.jpg?v=1791369141","url":"https:\/\/sorgiovannimotorsport.com.au\/products\/proflow-warlord-engine-block-cast-iron-ls-lsx-style-9-240-deck-4-000-3-880-3990-bore-steel-6-bolt-main-caps-each","provider":"Sorgiovanni Motorsport","version":"1.0","type":"link"}
